Abstract
Thread clamp for a warp end tying-in machine. In such a clamp, cam control means mechanically related to the remainder of the machine are provided for positively opening the clamps in order that the thread may be inserted therein without hindrance. The clamp is thereupon permitted to close and the mechanical means retracted therefrom in order that the clamp may be held in closed condition solely by the tension of adjustable resilient means applied thereto. With the mechanical means remaining inoperative with respect to the clamp, same is moved through a conventional operating cycle and back to its point of beginning. Mechanical means are thereupon again activated to open the clamp against the urging of said spring whereby the thread may be removed without restriction therefrom.
Claims5
In a thread clamp for warp end tying-in machines, comprising two clamping jaws, which are pivotal about pivot axes which are arranged parallel to one another, an abutment bar which is arranged between the clamping jaws and a spring for each clamping jaw, said spring pressing the clamping jaw against the abutment bar with an adjustable spring force and a control shaft for controlling the remaining parts of the warp end tying-in machine, the improvement comprising wherein for each clamping jaw there is provided an operating member which cooperates with said clamping jaw and which is controlled by the control shaft, said operating member lifting the clamping jaw off from the abutment bar at a selected point in the operating cycle.
